Excuse me if I post here. Maybe is a stupid question: why, instead of introducing except*, Python can't extend the functionality of except, so it can do what except* would do?
Good question. Here's an example: ``` try: . . . except OSError as err: if err.errno != ENOENT: raise . . . ``` If this would catch ExceptionGroup(OSError), the `err` variable would be an ExceptionGroup instance, which does not have an `errno` attribute. (Irit: Does the PEP answer this question? I couldn't quickly find it in the rejected ideas. I think it's a reasonable question and we should answer it, either in the Rationale or in Rejected Ideas.) -- --Guido van Rossum (python.org/~guido) *Pronouns: he/him **(why is my pronoun here?)* <http://feministing.com/2015/02/03/how-using-they-as-a-singular-pronoun-can-c...>
